  1. 21. Communities of practice or communities of discipline : managing deviations at the Öresund Bridge

    Författare :Andrew Schenkel; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Large infrastructure projects are seldom completed on time or on budget. Unlike many other projects of this type, the construction of the Øresund Bridge was considered to be a successful infrastructure project. Since no plan can foresee all events, deviations from plans arise, and these have to be managed as they appear during construction. LÄS MER

  3. 22. On Distributed Balancing of Wind Power Forecast Deviations in Competitive Power Systems

    Författare :Richard Scharff; Lennart Söder; Mikael Amelin; Gerard L. Doorman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; balancing; wind power integration; electricity market; wind power variations; wind power forecast errors;

    Sammanfattning : Wind power generation does, on the one hand, contribute to a less polluting and more sustainable electric power generation mix. On the other hand, the uncertainty and the variability of the power output do challenge the operation of the power system: hourly variations in wind power generation are hardly predictable in a precise way.

  4. 23. Lean Visual Management of Deviations in Product Development and Production - Coining Physical, Digital, and Hybrid Pulse Methodology

    Författare :Onur Kaya; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lean management; Visualization; visual management; lean tools.; issue management; deviation management; disturbance management; lean;

    Sammanfattning : Lean is a relatively new trend, and every company strives for lean aiming for creating more output while using less input by focusing on the customer via eliminating non-value adding waste. Lean started at Toyota within its production system. From production, it started to be used in product development, and later on to other various sectors. LÄS MER

  5. 24. On errors in meteorological data assimilation

    Författare :Magnus Lindskog; Erland Källen; Nils. Gustafsson; Florence Rabier; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Meteorology; Meteorologi; meteorologi; Meteorology;

    Sammanfattning : Data assimilation in Numerical Weather Prediction (NWP) optimally blends observations with atmospheric model data in order to obtain the best possible initial state for an atmospheric model prediction. Specification of error characteristics is an important part of data assimilation. LÄS MER

  7. 25. Application of Predictive Analytics for Shunting Yard Delays

    Författare :Niloofar Minbashi; Markus Bohlin; Behzad Kordnejad; Carl-William Palmqvist; Paola Pellegrini; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shunting yards; train delays; machine learning; simulation; freight transport; Godsbangårdar; tåg förseningar; maskininlärning; simulering; godstransport; Transportsystem; Transport Systems;

    Sammanfattning : Increasing the modal share of rail freight transport is one of the main ways to achieve carbon neutrality in Europe. The perceived low reliability and predictability of rail freight services is one of the main challenges to overcome in reaching this target. LÄS MER
